Falling Asleep at This Time May Protect Your Heart
Bedtime from 10 to 11 p.m. is associated with lower risk of developing heart disease
The time you go to bed may affect your risk for heart disease. In fact, researchers say, there is a heart health sweet spot for falling asleep: from 10 to 11 p.m.
An analysis of data from more than 88,000 adults tracked for around six years revealed a 12 percent greater risk among those who dropped off from 11 to 11:59 p.m. and a 25 percent higher risk of developing cardiovascular disease among people who fell asleep at midnight or later. Falling asleep earlier than 10 p.m. was associated with a 24 percent increase in risk, according to a report published Monday in the European Heart Journal—Digital Health.
"The body has a 24-hour internal clock, called circadian rhythm, that helps regulate physical and mental functioning," said neuroscientist David Plans, co-author of the study and head of research at Huma, a London health tech company that supports decentralized clinical trials.
